Form: 
 S + be+ past participle+by+O.
Meaning: passive
Usage: The passive is mainly used in 3 ways:
® When we don’t want to take responsibility for something.
E.g: The matter will be dealt with soon. (We don’t know or want to say who will dealt with it)
® When we want to focus on a happening, not who or what did it.
E.g: Our roof was damaged in last night’s storm. ( We are concerned about the roof)
® When we want to avoid “vague subject” like one, someone, they,
E.g: The form has to be signed.( not “someone/ one has to sign the form)
® However, the passive is not used when we want to focus on the person or thing that does the action.
E.g: You should finish this letter (not “ this letter should be finished)
